Application. filed February 1a, 1919.. Serial No. 277,878.

T 0 all whom t may concern Be it known that I, CHARLES GARLAND BRIDEN, acitizen'of the "United States, re sidin at 1752:;- North Vermont Avenue.in the clty of Los Angeles, county. of Los An geles, and State ofCalifornia, haveinvented a new and useful improvement in DemountableTire Rims, of which the following is a speciktication.

The invention is an improvement upon a demountable tire rim describedand claimed in my coJpending application Serial No. 256,613, filedlot.1, 1918, and an object of this inventiol-S to attain with greaterperfection certain. objects aimed at yin said former application.

Another object is to provide improved element which Will be acceptable'.to the trade as an accessory to be carried inst@ fk as a separatepunitand is so constructedtldg it may `loe adapted by slight changes, Whic.may be made in any ordinary well equipped machine shop, to fitdili'erent kinds ot demountable. tire rims. p

Another object is to provide 'for constructn ing a demountable rim ofthe open ring type with a minimum number of parts. A feature of theinvention in this respect is Vthe construction of the open ring rim insuch a manner as to allow direct seating ot the pins which carry thelocking and unlocking lever. p

ln this invention ll so construct the open ring rim that portions of therim body are `adapted to seat the `lever fulcrum pins directly.,

An 'object isto provide an open ring rim and lever combination thatwillhe cheap and simple, and that is applicable to prevent rim slippage onthe telly.-

Another object is to make provision whereby the rim may be collapsed tola titl maximum extent with a minimum stress and strain on the rim andwith minimized el'ort on the part ot the operator.

The invention includes novel parts and combinations of parts'fwhich goto make up the.A means for connecting the tire to the` telly. A

tither obgects, advantages and features of novelty; may appear :trom theaccompany- Patented May 23, 1922.

.The lever coinprises a thickened portion v1"' conforming to theconjoined slots when thel i'iiii is expanded. Ithe outer t'ace liot'lthc thicker portion also conforming to theouter face 1i ol' the webT when the rini is ex panded.

'lhe lever is provided with a handle 15' ot the saine width as thethickened portion l I i and which projects troni the inner end oi' the lthickened portion and contornis on its outer tace 16 to the inner faceot' the weh l". 'l`he first pin l() extends through the thickenedportion 12 ot the lever near the end of the` lever and' through theinward projections ot' the rini at the inner end ot' the tirst Slot Thepintle 11-extends through the thickened portion l2 at a distance t'rointhe outer ,end thereof about equal to twice. the length fot' the. slot5.

The two pintles 10 and Vl1. are about eqiiidistant from the joint 2where the two rini ends come together when the riin is ex` panded. Thesecond pin is at a greater dis` vtance from the inner end otl the secondslot, than from the outer end oi the secondslot.

and is spaced from the inner end of the tliiclt'ened portion a distanceabout equal to the distance troni said pintle to the inner end of thesecond slot so that the. riin may be Ylever to engage the telly band 18which is 'shown as provided with a hole 1S) for such engagement when therini is expanded and is seated on the telly hand.

The handle 15 is made somewhat longer than the thickened portion 1*. ofthelever and is adapted vto restas a stop against the outer lap 3 asseen in Fig. 12. when the rim is contracted practically to its fullestextent. and when the rim ends are lapped close to gether and practicallynested one within the other.

By bringing the riin ends close together as shown in Fig. :2 the hand iscontracted to exert torce in two directions. one of said. torces tendingto draw the terniinals of the band to the contracted position and theother tending to extend the inner teri-iiinal tangeiitiallv to pressagainst the outer ter niinal.v 'lhese two tin-ces exerted on thethickened portion through the incdiuni ot' the pintles. locks the handlroin springingr ont ot its contracted position; and .'onti'ai-iwise.when the.le\'er is swung in to tiring the thinner portion ot' handle 15against tliein` side vot' the riin. the spring tendency ot' the bandholds the lever in position with the outer side ot' the thickenedportion contornied to the outside otI the slotted web.

The leversniay I `be drop forged or otherwise formed andthe pin holes V25, bored as required.

' The lever shown 1n Fig- 1li is constructed .to he oun-iversalapplication to a variety 1 standard demountahle rirns.

"lhis form oi lever is provided with notch corresponding to the notch 23aiiovTe described and having its shoulder 23 formed by the laloriipt endof said notchpfpprovided `with a recess 27 adapted to seat a st-iid 28corresponding to the boss 17 shown in;l Figs. 2,4 '3 and ll for thepurpose ot engaginpj a hole .19 in the fellv band 18. lin this form or'lever a stud 29 shovvnpin Fig. 17 is provided with a stein 30 which maybe secured in the lever by forming therein a seat 3l. for theI stud.,

and a hole 32:.loored from said seat through ,the lever to accommodatesaid stein which may he secured therein by riveting.

L To apply this invention to closed ring rinus, such riins may he cuttransversely and stamped and bent to torni the slots and pin- .tleseats. 4

ln Figs. 14,16, 17, there is shown an oblongopening 33 in the handle oi'the lever unit to allow for theclearance of the valve stem 34. When thelever is applied to such type of rim as has the valve stern opening inclose proximity to the transverse division of such rim.

There is at present a'large number of open ring demonntahle tire rirnsin which the i transverse cut is made so close to the hole for the valvestem of the tire, that if the lever were made to turn toward such valvestem for expanding the rim, said valve stern would intercept the leverbefore it reached its closed position on the rim, and it such lever isprovided With a hole to accommodate the valve stern it is necessary tomake the lever so long that it Will not loclr in rim collapsed positionon account of contact with the collapsed band. A

l overcome this diicultyhy hinginp; the heel 35 of the lever tothat endof that open ring rim band which is pierced with the valve stem hole,and providing the lever with the elongate slot 33 to accommodate thevalve stern when the lever is turned into rim. collapsing position.

It is desirable that the lever he as short as possible with due regardto the requisite leverage for collapsing the' rin'i and in this devicethe heel of the lever is pivoted to that end of the rini which isprovided with the valve stern hole and with the shorter slot. lly thisarrangement of the slotted lef ver it is made'possible to equip withthis intention all manufactured rinis of the description specified, andto do this at a comL paratively slight expense.

feature ot' this invention, therefore lies in the specic constructionand arrange nient just specified. i

ln Fig'. 148 a notch 36 is providedin the inner side of the terminal ofthe thickened portion to adapt the lever to fit the telly in which thethickened portion of the lever acts a stop or loch in accordance withthe opening provided for such purpose in the telly hand. 1

An object is to conform the thickened portion o't the lever to theopening in' the telly band so throw to nest ,the lapped ends togetherwhen ,the rim is collapsed.

l elaine:-

1. in open ring demountahle tire ,rim slotted at both ends and providednear the inner end ot' one slot and at. about etpiidis` tance from theouter end of the other slot with pintle holes in the body of said rim;pins in said pintle holes and extending@i transversely ci' the slots;and a lever having,r

,hand in certain types as shown in Fig. '1l

as to give the lever a complete a thickened portion pivotcd on said pins'l respectively; said thickened portion being" practically equal'inlength to the length of both slots and filling; the open spaces, `formedhy said slots and havinpr a concave face cont'orniing to the curvatureof said rim when the riml is expanded; said lever terminating in ahandle having about the same' length as the thickened portion so thatwhen the handle is turned into collapsible position the ends of the rimmay be lapped close to each other.

2. A demountable tire rim o the open ring type provided at its ends withslots and With parallel projections at the sides ot' said slots formedby bending up inward extensions of the material of said rim; a leverhaving' at one end a thickened portion; the outer i'ace of whichcoiiforms to the curvature. of the outer face of the expanded rim; saidthickened portion conforming to the slots to close the same when itsouter face is flush with the outer face of the rim; a pintle extendingrthrough the thickened portion at one end ot the lever and through theextensions of the rim at the sides ot one of vband having both endsprovided with slots,

one of which is longer than the other; a lever having.; a thickenedportion 'fitting the combined slots and pivoted at one end to the bandnear the closed end of, the shorter sloty and pi-voted intermediately tothe band between the ends of the longer slot; said leverh ik A mien/1o..

being 'provided with a thinner portion of i the same width as thethickened .portion and vided with a .handle adapted to bring the bandends -in lapped position; the slot of the inner lapped ,end being ofgreater length than the slot of the outer lapped end for the purpose ofallowing the lever to be swung over sufficiently to cause the resiliencyof the band to kforce the endof the .-lever against the inside oftheband lso as to hold .the rim locked in contracted form.

5. The combination with a transversely divided slotted springdemountable rim .2Qband, slotted at both ends, of a lever having athickened portion pivoted in the slots and a handle adapted to rest as astop against the outer lap when the rim is contracted to its fullestextent.

6. A dexnountable rim comprising aspx-ing band divided transversely andslotted at both ends and having portions of the side walls of saidslots'turned inward to form pintle seats; and a lever pivoted in saidslots by pins extending through said seats.v

7. In a dem'ountable rim a transversely divided spring band slotted atboth ends and having the edges of the slots turned inward to form pintleseats.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 30th da of December 1918.
